Spectra before and after applying the model at maximum light. Top panel: 105 spectra in the absolute AB magnitude before correction (upper set of spectra) and after correction for intrinsic properties and color (lower set of spectra). An arbitrary offset has been applied for each set. The color code indicates the value of A_λ0. Lower panel: wRMS of the residuals for the uncorrected (in red) and corrected (in blue) spectra.
